Chromatic aberration
Photos below show clearly that the tested Nikkor doesn't show any traces of longitudinal chromatic aberration so you can assume it is corrected perfectly well.

Here the results are simply sensational because the highest level you deal with a level of just 0.02%. In our tests all results from 0.04% inclusive we consider to be very low so in this category the Nikkor deserves to be praised once again.

Spherical aberration
First photos of this chapter don't show any focus shift effect and it means spherical aberration level cannot be that high. The appearance of out-of-focus circles of light confirms that much – there are no visible differences between them. A slightly brighter centre of the circle we got before the focus is the only noticeable difference but, fortunately, such an effect is not very pronounced and doesn't give almost any reasons to lower our assessment in this category.
